Main research interest is in the field of physical chemistry, with interdisciplinary
connections to biophysics, medicine and microbiology. Research has been concerned with the
spectral and kinetic studies of ultraweak luminescence from biological systems using very
sensitive photon counting techniques. In addition the effects and functions of this weak
chemiluminescence are being studied.
